    • Abstract
  • According to the mechanism of roadway destruction by rock burst and the mechanical mechanism of rock roadway damage, the high porosity metal materials which have good properties of energy absorption, shock absorption and damping are applied in the roadway support. The paper establishes a macro "strong-soft-strong" mechanical mechanism model for roadway support and at the same time puts forward another "strong-soft-strong" model for soft structure-steel structure. ANSYS is used to simulate the mechanical properties and structural deformation of the tunnel under the action of rock-burst. The results show that material support for mine roadway stress has obvious buffering effect and the stress of roadway section decreases almost ten times, while the roadway deformation decreases obviously.
